Description

Technical Field

[0001] This utility model relates to the field of wire winding machine technology, specifically to a stress monitoring device for a PCCP vertical wire winding machine. Background Technology

[0002] Prestressed steel cylinder concrete pipe is a new type of composite pipe made by welding thin steel plates and socket joint steel rings into a cylinder, then pouring concrete inside and outside the cylinder using a vertical vibration method to form a pipe core (for small-diameter pipes, a horizontal centrifugal method can be used to form the pipe core inside the cylinder). After curing, circumferential prestressed steel wires are wound around the surface of the pipe core to establish circumferential prestress in the pipe wall concrete. Finally, a mortar protective layer is sprayed onto the outer surface of the wire-wound pipe core. The key process of wire winding is crucial to product quality, and the winding of circumferential prestressed steel wires is achieved using a vertical wire winding machine.

[0003] Existing wire winding machines have the following problems: the reliability of the wire winding stress process can only be verified by operators on a regular basis. When a fault occurs during the wire winding process, it cannot be effectively detected in the first time. There is a lack of real-time monitoring, which cannot effectively guarantee product quality and brings potential quality hazards to the product.

[0004] Based on the above situation, there is an urgent need for a PCCP vertical winding machine stress monitoring device to solve the problem of not being able to effectively guarantee product quality. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing wire winding machines rely solely on periodic calibration and inspection by operators to ensure the reliability of wire winding stress. When a fault occurs during the wire winding process, it cannot be effectively detected in the first instance, lacks real-time monitoring, and cannot effectively guarantee product quality, thus posing potential quality risks. This utility model solves the problem of not being able to effectively guarantee product quality.

[0006] The technical solution of this utility model is as follows:

[0007] The PCCP vertical winding machine stress monitoring device includes:

[0008] A wire winding mechanism is used to release the steel wire;

[0009] A rotary mechanism is provided at an interval from the winding mechanism, and a vertically placed core is mounted on the rotary mechanism;

[0010] A monitoring mechanism is located between the winding mechanism and the rotary mechanism. The monitoring mechanism includes a guide wheel and a stress sensor for detecting the stress of the steel wire, which is wound around the guide wheel.

[0011] Existing wire winding machines rely solely on periodic calibration and inspection by operators to ensure the reliability of the winding stress process. When malfunctions occur during the winding process, they cannot be detected effectively and immediately, lacking real-time monitoring and failing to guarantee product quality, thus posing potential quality risks. In this solution, the wire is released through the winding mechanism, and the rotating mechanism drives the core tube to rotate and wind the wire onto it. During the winding process, the stress sensor monitors the wire stress in real time, allowing operators to stop work and investigate the cause when abnormal stress occurs, thereby ensuring the winding effect and solving the problem of ineffective product quality assurance.

[0012] Furthermore, to facilitate automated adjustment of the prestress of the steel wire, one feasible solution is that the guide wheel is connected to a servo hydraulic rod controlled by a stress sensor. When this solution is adopted, the guide wheel is moved by the servo hydraulic rod, thereby enabling more precise adjustment of the prestress of the steel wire.

[0013] Furthermore, in order to facilitate the spiral winding of the steel wire around the tube core, one feasible solution is: the monitoring mechanism is connected to a lifting mechanism and a lifting wheel is installed on the lifting mechanism. The steel wire is wound around the lifting wheel. When this solution is adopted, the monitoring mechanism and the lifting wheel are driven to rise and fall synchronously through the lifting mechanism, so that the steel wire is spirally wound around the tube core.

[0014] Furthermore, this solution does not exclusively limit the specific structure of the lifting mechanism. One feasible solution is that the lifting mechanism includes a lifting platform and a threaded rod for driving the lifting platform. The threaded rod is connected to a lifting motor. When this solution is adopted, the lifting motor drives the threaded rod to rotate, thereby driving the lifting platform to rise and fall.

[0015] Furthermore, this solution does not exclusively limit the specific structure of the rotary mechanism. One feasible solution is that the rotary mechanism includes a base and a turntable mounted on the base. A rotary motor for driving the turntable is installed inside the base. When this solution is adopted, the rotary motor drives the turntable and the tube core to rotate synchronously, thereby causing the steel wire to be wound around the tube core.

[0016] Furthermore, this solution does not exclusively limit the specific structure of the wire winding mechanism. One feasible solution is that the wire winding mechanism includes a roller and a roller motor for driving the roller. When this solution is adopted, the roller motor drives the roller to rotate, thereby releasing the steel wire.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] 1. The steel wire is released through the winding mechanism, and the rotating mechanism drives the core to rotate and wind the steel wire onto the core. During the winding process, the stress sensor monitors the stress of the steel wire in real time, so that the workers can stop the work and find out the cause when the stress is abnormal, thereby ensuring the winding effect and solving the problem of not being able to effectively guarantee product quality.

[0019] Second, since the guide wheel is connected to a servo hydraulic rod controlled by a stress sensor, the guide wheel can be moved by the servo hydraulic rod, thereby enabling more precise adjustment of the stress of the steel wire;

[0020] Third, since the monitoring mechanism is connected to a lifting mechanism and a lifting wheel is installed on the lifting mechanism, the steel wire is wound around the lifting wheel. The lifting mechanism drives the monitoring mechanism and the lifting wheel to rise and fall synchronously, so that the steel wire is wound around the tube core in a spiral shape.

[0033] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0034] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0035] Example 1:

[0036] Please refer to Figure 1 The PCCP vertical winding machine stress monitoring device includes:

[0037] Wire winding mechanism 1 is used to release steel wire 2;

[0038] The rotary mechanism 3 is spaced apart from the winding mechanism 1 and a vertically placed core 4 is mounted on the rotary mechanism 3;

[0039] The monitoring mechanism 5 is located between the winding mechanism 1 and the rotary mechanism 3. The monitoring mechanism 5 includes a guide wheel 51 and a stress sensor 52 for detecting the stress of the steel wire 2. The steel wire 2 is wound around the guide wheel 51.

[0040] Existing wire winding machines rely solely on periodic calibration and inspection by operators to ensure the reliability of the winding stress process. When malfunctions occur during the winding process, they cannot be detected immediately, lacking real-time monitoring and failing to effectively guarantee product quality, thus posing potential quality risks. In this solution, the wire winding mechanism 1 releases the steel wire 2, and the rotary mechanism 3 drives the core tube 4 to rotate, winding the steel wire 2 onto the core tube 4. During the winding process, a stress sensor 52 monitors the stress of the steel wire 2 in real time, allowing operators to stop work and investigate the cause when abnormal stress occurs, thereby ensuring the winding effect and solving the problem of ineffective product quality assurance.

[0041] Specifically, in this embodiment, the stress sensor 52 is model S-20T, and the stress sensor 52 is connected to a display instrument 54 (S80 type). When this scheme is adopted, it is easy to observe. When the winding mechanism 1 is working, the comparison is displayed in real time. The display instrument 54 is equipped with a threshold (80% of the design force value). When it is lower than the threshold, the display instrument 54 will alarm.

[0042] The stress sensor 52 includes a storage module that can store stress winding data for one month or at least 1,000 pipe sections, which can be used as a reference for quality defect analysis.

[0043] This embodiment serves as a real-time comparison device for winding stress. It digitally displays the winding stress to operators and inspectors at all levels, completely resolving stress setting errors caused by malfunctions in the stress recording device of the winding machine or errors in stress calibration. It is part of the stress quality control measures, thereby effectively ensuring the quality of PCCP products.

[0044] Example 2:

[0045] To facilitate automated adjustment of the prestress of the steel wire 2, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, a servo hydraulic rod 53 is added. Specifically, the guide wheel 51 is connected to a servo hydraulic rod 53 controlled by a stress sensor 52. When this scheme is adopted, the guide wheel 51 is moved by the servo hydraulic rod 53, thereby enabling more precise adjustment of the prestress of the steel wire 2.

[0046] Optionally, in this embodiment, the stress sensor 52 is an ultrasonic stress sensor. When this solution is adopted, non-destructive testing of the steel wire 2 can be achieved.

[0047] Reference Figure 2 and Figure 3 In order to facilitate the spiral winding of the steel wire 2 around the tube core 4, one feasible solution is: the monitoring mechanism 5 is connected to the lifting mechanism 6 and the lifting mechanism 6 is equipped with a lifting wheel 61. The steel wire 2 is wound around the lifting wheel 61. When this solution is adopted, the monitoring mechanism 5 and the lifting wheel 61 are driven to rise and fall synchronously through the lifting mechanism 6 so that the steel wire 2 can be spirally wound around the tube core 4.

[0048] Reference Figure 3 This solution does not limit the specific structure of the lifting mechanism 6. One feasible solution is that the lifting mechanism 6 includes a lifting platform 62 and a threaded rod 63 for driving the lifting platform 62. The threaded rod 63 is connected to a lifting motor 64. When this solution is adopted, the lifting motor 64 drives the threaded rod 63 to rotate, thereby driving the lifting platform 62 to rise and fall.

[0049] This solution does not limit the specific structure of the rotary mechanism 3. One feasible solution is that the rotary mechanism 3 includes a base 31 and a turntable 32 mounted on the base 31. A rotary motor for driving the turntable 32 is installed in the base 31. When this solution is adopted, the rotary motor drives the turntable 32 and the core tube 4 to rotate synchronously, thereby causing the steel wire 2 to be wound on the core tube 4.

[0050] Reference Figure 6 This solution does not limit the specific structure of the winding mechanism 1. One feasible solution is that the winding mechanism 1 includes a roller 11 and a roller motor 12 for driving the roller 11. When this solution is adopted, the roller motor 12 drives the roller 11 to rotate, thereby releasing the steel wire 2.

[0051] Preferably, in this embodiment, the lifting motor 64 is a stepper motor. When this solution is adopted, it is convenient to make multiple lifting motors 64 drive the corresponding threaded rods 63 to rotate synchronously.

[0052] Preferably, in this embodiment, both the roller motor 12 and the rotary motor are servo motors. When this scheme is adopted, the amount of wire fed and wound can be adjusted more precisely so as to maintain the prestress of the steel wire 2.

[0053] Preferably, in this embodiment, the roller 11 is connected to a worm gear 13, and a worm 14 is provided on the output shaft of the roller motor 12 and the worm 14 cooperates with the worm gear 13. When this scheme is adopted, due to the self-locking property of the worm gear structure, the steel wire 2 can be prevented from driving the roller 11 to rotate, thereby adjusting the amount of wire feeding more accurately.

[0054] To address the issue of ineffective product quality assurance, this solution involves releasing the steel wire 2 via the winding mechanism 1, which in turn drives the core tube 4 to rotate and wind the steel wire 2 onto the core tube 4. During the winding process, the stress of the steel wire 2 is monitored in real time by the stress sensor 52, allowing workers to stop operations and investigate the cause when abnormal stress occurs, thereby ensuring the winding effect and resolving the problem of ineffective product quality assurance.

[0055] In order to adjust the stress of the steel wire 2 more precisely, in this solution, the guide wheel 51 is connected to a servo hydraulic rod 53 controlled by the stress sensor 52. The servo hydraulic rod 53 drives the guide wheel 51 to move, thereby enabling more precise adjustment of the stress of the steel wire 2.

[0056] In order to facilitate the spiral winding of the steel wire 2 around the tube core 4, in this scheme, since the monitoring mechanism 5 is connected to the lifting mechanism 6 and the lifting mechanism 6 is equipped with a lifting wheel 61, the steel wire 2 is wound around the lifting wheel 61. The lifting mechanism 6 drives the monitoring mechanism 5 and the lifting wheel 61 to rise and fall synchronously, so that the steel wire 2 can be spirally wound around the tube core 4.
